To all whommay concern.' i

Be it known that l. AUGUST SVNDH, a citizen of the United States, residing at Yonkers. in the county of lVestchester and State of New York, have invented a new and useful In'lprox-emcnt in Sidewalk Endless Ash-Conveyors, of which the following is a specification.

My invention relates to an ash ho1st-or elevator especially adapted for elevating ashes from a compartment beneath a sidewalk up through an opening in the walk and depositing` them in a wagon or cart at the curbstone.

One of the objects of the inventiony is to provide a device of this character in which the ashes are automatically elevated by an endless conveyor from a pit or receptacle where they may loe placed when removed from the furnace. and deposited in a wagon without any further handling being required.

Other objects of the invention will appear hereinafter., the novel combinations of elements and Lirrangement of parts being de- `fined in the appended claims.

ltefr-:irring` to the drawings in which issl'aown a construction embodying my invention, Figure 1 is an elevation of the hoisting device, and showing in section a sidewalk and the compartment beneath it in which the device is installed: Fig. 2 is a. fragmentary view showing the winding drums and their connection to the conveyor supporting, frame; Fig. 3 is an end view of the chute at the upper end of the conveyor; and Fig. L1 is a view on an enlarged scale of a portion of the endless convey'er and guide sprockets therefor.

he elevator is preferably located in a place convenient to the furnace or furnaces from which the ashes must be taken, and in this instanceis shown installed in a compartment 1 located beneath the sidewalk 2. The portion of the walk 2 over the compartment 1 may be supported by a framework comprising horizontal I-beams 3 secured to the foundation wall 4f and supported at their outer ends by vertical I-beams or supports 5. These vertical supports 5 rest on the cc- Incnt floor 6 of the compartment 1. The compartment 1 communicates through' a door or passageway 7 formed in the wall 4 with a hasementor cellar in which may he l0- cated the furnaces.

the sidewalk.

The endless conveyor 8 when in use extends upwardly through an openingI 9 in When the conveyor `is not in use it is lowered into the compartmentl 1 and the opening ti .is closed by a trap door or cover l0. 'l`o the under side of the cover 10 are secured vertically depending' rods 11 which are guided in their vertical movements by clips or guides 12. To the lower ends of the rods 11 secured a framework for supporting the conveyor. This framework ycomprises a horizontal cross bar or hars 13 secured to the lower ends of the rodsl 11, upwardly extending pieces 14 and an upper cross bar 15 securcdto the pieces 14.

The cover 10 and parts connected thereto are liftedand lowered by the followingl means. Horizontal rods. 16, 1G (Fig. 2) secured in the framework k3 and extending on opposite, sides of the rods 11 have journaled thereon winding drums 17 and ,18.

-lopcs or cables 19 are attached to these drums and have their outer ends secured respectively to lugs or projections 2O and 21 on the cross har 18. Secured to the drum 17 are two sheaves or pulleys 22, 23, and cured to the drum 18 isa sheave 24 in alinement with the sheave 23.- The sheaves 23 and 24 are connected for simultaneous rotation hy an yendless chain 25 passing over the sheaves.

Secured to the wall 4 is a bracket26 carryying a pinion 27, al crank 28, a gear wheel 29 meshing with the pinion. Aand a sheave '30 secured to the gear wheel An endless chain 31 forms a driving connection be tween the' sheaves 30 and 22. A counterweight W is attached to one end of the cable 'any suitable source of power` In this case I have shown them connected to an electric motor M through a train of speed-reducing gearing 38. The drive wheels 37 are located in a pit or depression 39 formed helow the level of the floor 6. The gearing 38 may be separated from this pit by a parti tion 40 to protect the gearing from contact with the ashes. 4The motor M is controlled by a switch S in the; motor circuit.

The conveyer 8 extends upwardly vertically from the drive wheels 37 to sprocket wheels 41, 42 carried by the cross bar 15. Pivoted on the shaft of the sprocket wheel 41 is a pair of arms 43 extending upwardly therefrom, and at the upper ends of these arms are sprocket wheels 44 spaced apart to permit the buckets 36 to pass between them as indicated in Fig. 4. The arms 43 are held in any position desired Aby means of a chain 45, the diterent links of which may be caught on a hook 46 to adjust the inclination of said arms. At the upper end of the conveyer is a chute 47 pivoted co-axially with the wheels 44 and adjustable to any desired angle with the arms 43 by means of an arcshaped bar 48 provided with a series of holes rand a pin 49 passing through one of said holes and a hole in the arm 43. In order that the chute 47 may be folded down yin line with lthe arms 43 as indicated in' dotted lines in Fig., 1, the bottom ef the chute is made in the form ofa door 50 (Fig. 3) hinged at 5l. When in use this door is held closed by a pin 52, and when not in use it is swung back parallel with the side of the chute as shown in Fig. .3, permitting the chute to fold do'wn'over the conveyerv In operation, when the parts are in the position shown the drive wheels 37 will be rotated in a. clockwise direction carrying the buckets 36 through the pit 39 where they will each pick up a -lo'ad of ashes or 'other `material that may be in the pit and convey it to the chute 47, where the buckets are emptied in passing over -the wheels 44 and the ashes slide down the chute into a wagon 55. The upper endof the chute is in the formof a hood extending over the wheels 44 and preventing the ashes lfrom being scattered by the wind as they are emptied from the buckets. After use, the switch S is opened to stop the motor, -and the conveyer lowered into the compartment -1. In doing this the chute 47 is first folded into line with the conveyor, and the upper section of the conveyer brought into vertical alinement with the lower section, as shown in dotted lines in Fig. 1. The crank 28 is then turned in a direction to unwind the ropes 19 from the drums 17, 18, -which will permit the cover 10 and the parts connected therewith to descend by lgravity until the cover is -in position to closethe opening 9 and the conveyer entirely beneath 'the sui'- faceof the walk. As the rope 19 unwinds from the drum 17 the rope 32 is wound on the drum 18, lifting the counterweight which is lpreferably made sutliciently -heavy to substantially balance the parts.

I have shown and described a device intended especially for handling ashes, but in is obvious that it might be used for conveying other materials, and also that it might be adapted to the varying conditions found in different localities, by changes in the positions and arrangement of parts which would suggest themselves to those -skilled in the art, and that various changes in the details of construction and arrangement of parts might be made without departing from the spirit and scope of the invention. I desire, therefore, not to be limited to the precise construction disclosed, but
